Here's what im not understanding from this conversation... why does a cnc have to be one size fits all? Why are cnc porters only using one specific port program on one particular head? I wrote over a dozen cnc programs just today. Are these guys lazy? I would have a whole list of different programs for each application if that was my bread and butter.
